I would say your parents are short sighted. While I wouldn’t want you vaping either, to short circuit your education is just plain dumb. As long as your grades are good and your progressing towards graduation, I’d kick you butt, but send you right back to school. So in reality, you need to convince them that you know what you did was stupid, but you don’t want to jeopardize you education. And like others have suggested, if they don’t start cutting the cord, have a plan. Good luck.
